Please note that

• If you are connected to SISSA network with your laptop you can use mathematica using mathlm.sissa.it as license server.
• It is the same using VPN at home (you are using SISSA network in this case too)

If you have a SISSA account (NOT a guest or visitor one) you can have a mathematica home license (you can use it without a network connection). Use the following procedure:

• If you don't have an account at Wolfram user portal, you must create a new one. Follow this link:

https://user.wolfram.com/portal: here you must USE ONLY YOUR SISSA email, NOT an external one! (but DO NOT use the same password you have in SISSA!)

• Once created your Wolfram account follow this link to ask for an activation key:
  

Students and PostDoc (assegnisti di ricerca) Activation Key Form
Scientific Staff Activation Key Form

• As you fill the previous form you will be redirect to you activation key page. In the future, when you connect to your wWolfram account, you will see your Activation Key in your “My products and Services” link.
• You can download your Mathematica Software from your Wolfram account, following “My products and Services” link.
